So what i'm going to do next is transfer my /home, the whole MaryAnn

culprit list.
If that doesn't fix it, then its something to do with the graficks.
I have one real clue, some one the openscad list said the preview mode
opened a bunch of gfx buffers it used the preview mode that it didn't
do in final build mode, so I ran some tests on a fairly complex
project, noting that the openscad logging window said a preview was
done in a bit over a second but the final monocolored version took
over 9 seconds to render, giving me an image I could move in 3d space
in the preview window in real time. But that 1.2 second preview
render took 30 to 45 seconds to show in\on screen and every update of
that image took at least 45 seconds to register on screen, and during
that 45 seconds or more, openscad was frozen from all other input.
That is as close to a clue as I have, also manifested when any kind of
a file requester needs to be drawn on screen it is subjectto to that
same time killing lockup except it might be as long as 5 minutes
before the requestor is drawn on screen. That raid was built by
buster, worded fine for bullseye, but seems to be a disaster for
bookworm, yet an fsck finds nothing wrong.
Those are the clues I have. Nothing obvious and common to all this
contaminates the logs.
I own the whole nearly 1.8T raid10, every byte of it. Why can't I use
it? Instead its holding me for an undefined ransom in time that I at
89 don't have a lot of left.
I assume this is the computer with the Asus PRIME Z370-A II motherboard,
Intel i5-9600K processor, 32 GB RAM, WD Black 2 TB NVMe PCIe 3.0 x4
SSD, a few PCIe x1 SATA III HBA's with many ports, many SATA III SSD's
and/or HDD's, and a few md RAID (?).
Yup, I just added another 3.6Tb of sdd's that are still unformatted.
Gigastone's from Taiwan.
Did you connect the /home RAID10 4 @ 1 TB SSD's to one PCIe x1 HBA?
I assume its an X1 card, small footprint, cheap version with 10 bondouts
but only 6 have drive cable sockets installed. Only 4 for the raid10 are
actually used. I have another card I haven't tried, is a full 16 ports
but is also the narrow pci-e footprint. Neither is sold as a raid card,
so its all mdadm.
This worked perfectly for buster and bullseye, so it seems this problem
is bookworms problem.
Are your file systems full?
/home is currently about 20% used, everything else is much lower yet.
# df /boot / /tmp /home
The whole thing:
gene@coyote:~$ df

Do your file systems need defragmenting?
# e4defrag -c /boot / /home
dnk, wasn't fam with how to do it, And worst case score for that cmd is 1.
/home was the last check:
